Researchers using x-ray technology discovered hidden artwork beneath one of Pablo Picasso's Blue Period paintings, National Geographic reports. The 1902 painting La Misereuse Accroupie (The Crouching Beggar) analyzed by a team of researchers from U.S. and Canada revealed Picasso painted over a landscape portrait by an unknown artist.

Flashback: In 1957, Picasso said that x-ray technology might be used to reveal a hidden work in one of his earliest paintings.

The technique, called x-ray fluorescent spectroscopy, showed Picasso rotated the artwork of a Barcelona painter 90 degrees to be able to use the lines of the landscape form to create his final composition.

Why it matters: "[W]e can get into the mind of the artist and better understand the creative process," said Marc Walton, a research professor of materials science and engineering at Northwestern University.

One curious finding the researchers discovered is "the unexpected presence of an awkwardly positioned hand holding a disc," NatGeo writes. "We can see that he was wiping off the paint and working to position the fingers,” Walton, who helped develop the x-ray tool, told NatGeo.

The Pac-12, which includes universities in Arizona, California, Colorado, Oregon, Utah and Washington state, will play football starting Nov. 6, reversing its earlier decision to postpone the season because of the coronavirus pandemic.

Why it matters: The conference's about-face follows a similar move by the Big Ten last week and comes as President Trump has publicly pressured sports to resume despite the ongoing pandemic. The Pac-12 will play a seven-game conference football season, according to ESPN.

Global coronavirus vaccine initiative launches without U.S. or China

A global initiative to ensure equitable distribution of coronavirus vaccines now includes most of the world — but not the U.S., China or Russia.

Why it matters: Assuming one or more vaccines ultimately gain approval, there will be a period of months or even years in which supply lags far behind global demand. The COVAX initiative is an attempt to ensure doses go where they're most needed, rather than simply to countries that can produce or buy them at scale.
